Anyone Help!! Amp not working right

Hello everyone I have an issue that I have just discovered today while I was on my way to school..

Alright I have a Hifonics TX1005D Amp, but today I notice that the remote that goes in the front where you adjust bass is not lit, So while on my way to school I go in my glove box take out a new one because I taught it was bad, plug it in and blue light lights up great.. I get to school and there is no more light??? AGAIN???

Okay when I turn on my stereo amp goes on protect light goes on and then off and power light lights up.

Subs work bass is there, if i unplug the whole controller completely from amp and all bass still works..

I added a capacitor a couple weeks ago but that is wired positive from batt to CAP n then to AMP and AMP n CAP have diff negatives.
